RESILIENT TIRE.

Application filed October 6, 1913.

To all whom it may concern Be it known that I, CLYDE S. Mouse, a citizenof the United States, residing at De Kalb, in the county of Dekalb,State of Illinois, have invented certain new useful Improvements inResilient Tires, of which the following is a specification.

This invention relates to improvements in resilient tires, and while itis more particu larly intended for use on the wheels of automobiles yetit is applicable for use on the wheels of other vehicles of variouskinds, and it consists in certain peculiarities of the construction,novel arrangement and oper ation of the various parts thereof, as willbe hereinafter more fully set forth and specifically claimed.

The main object of the invention is to provide a resilient tire whichshall be simple and inexpensive in construction, strong, durable andeflicient in service or operation and so made that its resiliency andefficiency will not be materially afiected by punctures and blow outs.

Another important object of the invention is to provide a resilient tireof such construc tion and arrangement of its parts that if desired thetire casing or tube of an ordinary pneumatic tire, whether new or used,or of high or low grade material, may be employed as one of the elementsof my improved tire.

Various other objects and advantages of the invention will be disclosedin the subjoined description and explanation.

in the accompanying drawings which serve to illustrate an embodiment ofthe invention, Figure 1 is a side face view partly in elevation andpartly in section of a resilient tire embodying one form of theinvention, showing the parts thereof assembled and ready to be placed onthe felly of the wheel. Fig. 2 is a greatly enlarged circumferentialsectional view of a portion of the felly of a wheel, showing a part ofthe tire mounted thereon; said section being taken on line 22 of Fig. 3looking in the direction indicated by the arrows. Fig. 3 is a crosssectional view taken on line 3-3 of Fig. 2 looking in the directionindicated by the arrows. Fig. t is a bottom plan view taken on line 44of Fig. 3 looking in the direction indicated by the arrows. Fig. 5 is adetached perspective view of one of the chambered resilient blocks usedin the construction of the tire. Fig. 6 is a similar Specification ofLetters Patent.

view of another one of the resilient blocks employed in conjunction withthose shown in Fig. 5; and, Fig. 7 is a circumferential sectional viewof a tire and a part of the felly of the wheel showing the formermounted on the latter; said view being taken on line 2-2 of Fig. 3looking in the direction indicated by the arrows, and showing amodification in the construction of the tire.

Corresponding numerals of reference referring to like parts throughoutthe different views of the drawings: The reference numeral 10 designatesthe casing of the tire, which casing may be of the preferred or ordinarykind such as that employed in pneumatic tires in common use, and saidcasing may be made of any suitable flexible material. As shown in Fig. 3the casing 10 is split circumferentially on its inner periphery so thatwhen in position on the felly the edges of the casing will beapproximated, thus forming substantially a cylindrical tube. Near eachof its edges the casing is provided with a laterally extendedenlargement 11 which engage a channelled rim 35 as will be presentlyexplained.

Located concentrically within the casing 10 is a resilient metal band 13which has its ends beveled as at 14,-see Fig. 2so as to overlap eachother. This band as shown in Fig. 3 is provided at each of its edgeswith an inturned flange 145, which flanges assist in holding in positionan auxiliary and expansible band 15, and also a spring 16, which assistsin the expansion of the band 15 as well as the band 13. The band 15 isbroken and is provided at each of its ends with a slightly reducedportion 17 around which reduced portions the spring 16 is wound so as torest at one of its ends against shoulders 18, and at its other endagainst shoulders 19 on the approximated ends of said band. Each of theextensions 17 is provided at its free end with a catch or deflectedtongue 20 to engage ratchet teeth 21 formed on the surfaces of the band15 to engage said tongue.

interposed transversely of the casing 10, between the inner surface ofthe outer periphery thereof, and the band 13, are a series of chamberedblocks 22, each of which is preferably made of rubber and segmental inshape as is clearly shown in Fig. 5 of the drawing. Each of the blocks22 is provided with apertures 23 which extent transversely through themiddle portion of said block. Each of the blocks 22 is provided with atransverse slot 24 which divides the lower portion of the opening 23 inthe block and permits of greater resiliency thereof. Each of the blocks22 is provided at each of its ends with an extension 25, whichextensions will lie between the flanges 14 of the band 13 and the tirecasing, as is clearly shown in Fig. 3 of the drawings. As shown, theblocks 22 are spaced apart and between each of said blocks is locatedand frictionally held thereby a movable block 26, each of which is alsosegmental in shape, and preferably made of resilient material such asrubber. The blocks 26 are of less size than blocks 22 so as to affordspaces 27 between the inner or straight edges thereof and theoutersurface of the band 13. These movable blocks 26 close the chambers23 or openings of the blocks 22 but do not close the slots 24 in thelast named blocks. Thus it'will be seen that the chambers or openings 23will be in communication with one another through the slots 24, and asthe blocks 22 and 26 are extended completely around the casing 10 andbetween it and the V band 13 a series of chambers will be formed orprovided.

Located within the casing 10 near its inner periphery is an expansibleband 27 which is preferably segmental in cross section as'shown in Fig.3, and has at each of its edges an inturned flange 28 to prevent injuryto the tire casing and also to rein force said band, The band 27* isbroken and has its ends beveled as at 29, see Fig. 2, so as to overlapeach other. This band is also provided at proper intervals through itsinner portion with slots 30 for the reception and retention of wing nuts31, each of which is provided with a sleeve 32 to engage a screw bolt33, each of which bolts has a head 34 thereon to rest against the innerperiphery of a metal rim 35 which is provided at each of its edges withan inturned flange 36 to engage the extensions 11 and the approximatededges of the tire casing. The metal rim 35 is provided at proper pointsto register with the slots 30 in the band 27 with a series of openings37 through which the bolts 33 are passed.

The felly 38 of the wheel may be of the ordinary construction andmounted upon spokes 39 in the usual manner, but in order to permit theband 35 to fit closely on its outer surface, said felly is provided witha series of transverse recesses 40 for the reception of the bolt heads.

In Fig. 7 of the drawing is shown a modification in the construction ofthe tire, which is identical in every respect with the constructionabove described and shown in Figs. 1 to 6 inclusive of the drawingsexcept that the expansible band 15 is omitted and an expanding spring 41is substituted for said expanding band. This expanding spring 41 willperform the function of the expansible band 15 and the expanding springthereon, that is, it will assist in expanding the band 13 which supportsthe chambered blocks.

As is clearly shown in Figs. 2, 3, 4, and 7 of the drawings the felly 38is provided with a tube 42 of the ordinary kind used in connection withan air pump for forcing air into pneumatic tires. This tube is shown tobe closed by a screw plug 43 and connected with an opening 44 in the rimor band 35 which latter opening registers with an opening 45 in the band27 so that a key or rod 46, after the plug 43 has been removed from thetube 42, can be inserted through said tube 42, and the openings 44 and45, see Fig. 2, and into the openings 47 and 48 formed in the reducedportions 17 of the band 15, thus holding the said band in a slightlycontracted position until the blocks 22 and 26 shall have been placedbetween the band 13 and the tread portion of the tire casing, afterwhich it is apparent that the key 46 may be withdrawn, when it isapparent that the spring 16 will expand band 15 and also the band 13 soas to force the blocks 22 and 26 against the tire casing in whichposition they will be maintained by the action of said spring and bands.After the key 46 has been withdrawn the tube 42 may be closed by theplug 43 to exclude dust and foreign matter from the tire.

From the foregoing and by reference to the drawings it will be readilyunderstood and clearly seen that by employing a tire embodying myimprovements great eiiiciency, durability, resiliency and economy willbe afforded, and that if the tire casing is punctured or badly cut aresilient tire will still be furnished by reason of the resilientblocks, and the air chambers or pockets provided by the same. While Ihave shown and described my invention in its preferred embodiment, I donot wish to be limited to the same, nor to the details shown, since itis obvious that various shapes of blocks may be used, and numerouschanges might be made in the construction and arrangement of the partswithout departing from the spirit of my invention.

As there is considerable space between the band 27, spring 16, bands 13and 15, it is apparent that an air space or cushion will be provided.

Having thus fully described my invention, what I claim is new and desireto secure as Letters Patent is- 1. In a resilient tire, the combinationwith a circular casing, of an expansible band located therein at adistance from the tread portion of the casing, means to expand saidband, a series of chambered resilient blocks and a series of solidresilient blocks alternately located in contact with one another betweensaid band and the tread portion of the casing, said chambered blockshaving lateral extensions interposed between the sides of the casing andthe sides of the band, and said solid blocks being located at a distanceexternally of said band.
